The present application relates to an optical film and a method for producing a polarizing plate. The present application can provide an optical film satisfying optical and mechanical durability required in a polarizing plate effectively and capable of forming a polarizing plate without causing bending when applied to a display device, and a method for producing a polarizing plate to which the optical film is applied. The present application can provide an optical film capable of realizing the required optical and mechanical durability without causing bending even in a polarizing plate applied to a thin display device and/or a thin polarizing plate, and a method for producing a polarizing plate to which the optical film is applied.

Production method of optical film

The present application relates to a polarizing plate. The present application can provide a polarizing plate having excellent optical and mechanical durability even when it is formed in a thin thickness or is applied to a thin display device and without causing bending or twisting when applied to a display device.

Polarizing plate

The present invention relates to a polarizing plate, a liquid crystal panel and a display device, and more specifically to a polarizing plate including a polarizer, and a hard coating layer having a thickness of 10 μm or less and a light-transmitting substrate which are positioned so as to face each other on the basis of the polarizer, and to a liquid crystal panel and a display device including the same.

Polarizing plate, liquid crystal panel and display device

The present application relates to a polymer film and a method for producing a polarizing plate. The present application can provide a polymer film satisfying optical and mechanical durability required in a polarizing plate effectively and capable of forming a polarizing plate without causing bending when applied to a display device, and a method for producing a polarizing plate to which the polymer film is applied. The present application can provide a polymer film capable of realizing the required optical and mechanical durability without causing bending even in a polarizing plate applied to a thin display device and/or a thin polarizing plate, and a method for producing a polarizing plate to which the polymer film is applied.

Production method of polarizing plate

The present application relates to a polarizing plate having a polarizing film in which a light absorption axis is formed in one in-plane direction; a protective film formed on one side of the polarizing film; and a pressure-sensitive adhesive layer formed on the other side of the polarizing film, where the total thickness is 200 &#x3bc;m or less, and a ratio of (S/S) of a shrinkage force (S) of the polarizing film in the in-plane direction parallel to the light absorption axis direction and a shrinkage force (S) of the protective film in the in-plane direction perpendicular to the light absorption axis direction is in a range of 0.1 to 5. The present application can provide a polarizing plate which does not cause cracks or the like while having a thin thickness, does not induce warping or twisting in itself and does not induce the above problems even when applied to a display device such as an LCD or OLED.
